TECHNICAL FIELD

Exemplary embodiments according to the present disclosure relate to abox holder, and more particularly, to a box holder capable of packingproducts and items in a clean and safe manner without damaging a boxduring the packing of the products and the items into the box.

BACKGROUND ART

Conventionally, papers of various kinds (corrugated cardboard,cardboard, etc.) are manufactured into a planar sheet of packaging boxwhich is then folded into a three-dimensional packaging box in sequence.After a product is put in the three-dimensional packaging box, the boxis sealed at the top and bottom by machine or a simple jig using a steelfixing pin such as a stapler pin and shipped. To unpack the shippedpackaging box, at least 12 pins need to be removed from the top andbottom of the box. However, it is inconvenient to remove the staplerpins. Moreover, because the pins are sharp, hand may be injured and thesurface of the packaging box may be damaged during the removal of thepins, making it impossible to reuse the box. While the top and bottom ofthe box may be sealed by an adhesive, this could also damage thepackaging box as the surface of the packaging box may be torn off duringthe unpacking of the box.

As shown in FIG. 1, a packaging box (10) generally has a first cover(11) and a second cover (12) on an upper surface or a lower surface, thefirst and second covers facing each other to form an inlet. Once productis received through the inlet, the first cover (11) and the second cover(12) of the packaging box (10) are folded together at the inlet to sealthe box. The inlet is sealed with a tape (20, see FIG. 2) along edges(111, 112) to sealingly pack the box. However, as shown in FIG. 3, whena tape (21) is applied along edges (111, 112) of the first cover (11)and the second cover (12), the edges (111, 112) may be detached toprevent a complete sealing of the box. To solve this problem, most userswould wind the tape (21) around the box while pressing down the edges(111, 112) of the first cover (11) and the second cover (12) with a footor hand.

Korean Utility Model Publication No. 20-0393769 (hereafter, referred toas “Prior Art Document 1”) discloses a device for folding a packagingbox manufactured from papers of various kinds (corrugated cardboard,cardboard, etc.) to be provided in the form of a planar sheet which isthen folded into a three-dimensional packaging box in sequence.
